I h all iii/2 0122 it may concern:

Be it known that l, ()riro M. tl'r'rn, citizen of the United States. residing at the city of Jamestown, n the county of Chautauqua and State of New York. ha vc invented certain new and useful ln'iprovenients in AnlomobileLamps, oi. which the following, taken in connection with the accompanying drawings. is a specification.

The invention relates to lamps for vehicles and similar constructions wherein it is d sired to throw the light to a distance; and the object of the improvement is, first, to provide a lamp with a compound parabolic shaped reflector in which the light emitted from the lamp is projected in one direction, being controlled by the conformation of said compound reflector and a lens and complementary reflector within said compound parabolic shaped reflector; and second,'to prm ide a vision protecting screen of several series of intercrossing wires which form parallel tubular openings for the parallel rays of light which form thelight shaft; third, to provide a tubular holder for said lens and a complementary ring re lector on said vision protecting screen of wire in front of the lamp; and fourth, to provide means for the quick and eas assemblage of said intercrcssing wires which form said Vision protecting screen; and the invention consists in the novel features and combinations hereinafter set forth and claimed,

in the drawings, Figure l is a vertical (liametral sectional view of the lamp from front to rear showing the construction and arrangement of the different parts and their relation to one another with the wire vision protecting screeii in the front cylindrical portion of the lamp, and the tubularholder tor the lens and ring reflector on said vision protecting; screen. Fig. 2 is a perspective view of the tubular holder for the lens showing the complementary ring reflector on the rear end of the same. Fig. 3 is a perspective view of the slotted assembling block for the spaced intercrossed wires which form the vision protectingscreen, showing the wires extending out therefrom in dotted line before bending for attachment within the' tubular holder for said vision protecting screen; and Fig. 4 is a perspective View of a portion of the assembling block showing the preferred manner of slotting the some and also showing the wires extending beyond the sides 0' the block.

Like characters of reference refer cor- 'tujllfllltllllg parts in the sev ral views. I

.l he numeral it! designates the outer shell or casin of an ordinary parabolic shaped :zulom le lamp, which casing is preferably made of thin sheet metal. and has a large open t'ront which is, as normally constructed, closed by a. glass 11, which glass is held in pl. :c by a, rim l2, pre zel-ably with a rubber sket 13 beneath the same and between saio I ss and the sp ling flange 14.

airing flange L is formed around the outwardly turned e e of the inner reflector shell 15, an. annular groove 16 being pz'o- Io vided in the flange A to receive the gasket 13 therein. The flange lat holds the shell or outer casing 10 in spaced relation to the inner reflector shell .15, and the two shells 10 and 15 are made in substa itiaily the same 7 parabolic shape, the shell 15 being; sntlicientlysmallcr to permit beingl id in spaced relation within the outer shell in by means of the flange 14 at the front and the spacing ring 17 between said shells near the rear portion, thereby supporting all the parts of the lamp firmly in position.

The central portion or parabolic retlcctor l5 therein surrounded by a c to which a small reflector inserted by being sprung into the curve nge 19 thereby holding the reflector 20 iii .aly in position upon and so related to the parabolic reflector 15 that -while itis oi a higher c thereby forms a compound 7 tiector of the two reflectors 15 an also closes the opening 18 in such a manner as to be substantially continuous with the parabolic reflector 15.

A slightly larger opening 21 is in the rear end of the casing it which the small reflector 20 may be which opening 21 is closed by means of screw cap which has a handle i turning the cap into the screw thread pi vided in the casing 10 around the open It is apparent that the screw cap may be easily removed by unscrewing sai e thereby opening an approach to reflector 20 for t 1 adjustment and r of the same.

An electric lamp is mounted in a holder 26 in'the center of the small retfi 2:; and has the connecting wires 2? l0; to tl conce ot' electrical energy. 'lth t when mounted in the r end of the opening 18 tango 19 1n- 26 is so adjusted in relation to the reflectors 15 and 20 that the center of the light in the lamp 25 is at that point which will be best reflected by the two reflectors in their relation to each other. T he curves of both the reflectors l5 and 20 are such that substantially all the rays of light are reflected in parallel lines thereby projecting a strong beam of light upon the roadway in front of the vehicle.

In order to protect the vision of the bystander or passer-by from the dazzling glare of the lamp, .a removable or detachable vision protecting screen is provided which consists of the three series of intercrossed wires 30 in the sheet metal cylinder 28. The cylinder 28 has the flange 29 for attachment of the screen to the lamp by means of the rim 12 in place of the glass 11 which is usually held by said rim 12. The glass 11 is placed in front of the cylinder 28 and held there by means of a rim 39 similar to rim 12, which is partially broken The interior of the cylinder 28 is filled with three intercrossing series of horizontal and vertical wires which cross one another in spaced relation thereby forming square or rectangular spaces between said wires, said series of wires being spaced gradually nearer to one another as theydraw nearer the light 26 to increase the tubular eilect.

The wires 30 are arranged in the intercrossed spaced relation by means of an assembling block 31, which assembling block has the slots 32 extending nearly through said block 31 at substantially right angles.

The wires are received in the slots 82 in the desired spaced relation to one another and intercrossing one another and extend slightly beyond said block in order that, after the wires are inserted, it may be turned against a straight edge thereby turning the extended wire ends into the circular form shown at 33 in Fig. 1. The entire screen is then dipped in solder thereby fixing all the wires in their intercrossed relation to one another. l Vhen the ends 33 oi the wires 30 are turned the wire core. fits closely within the tube 28 and is attached thereto, thereby providing square or rectangular apertures thrmigh which the light is freely reflected.

The light is further reflected, and protected by a short tube 3a which is attached to the inner side of the wire screen in front of the lamp by means of a flange 35. The tube 3lhas an annular groove which receives therein the retracting lens 37. The

tube 34; also bears on its inner end the complementary ring refractor 38 which aids the small reflector 20 in so controlling thelight as to project the light rays through the tube and lens 3?, being retracted by said lens into parallel alineinent'with the re niaining rays of light.

...t is obvious that the vision protecting nee lee struction which can be attached easily and quickly to the common forms of automobile lamps.

The spaced wires 30 of the vision protect ing screen in their series relation to one another form, as it were, tubular openings in the interstices therethrough from front to rear through which the light is freely refiected, the only obstruction being the small wires of which the screen is constructed.
